If you take this movie for what it is - superhero action based on a comic book - then you will not be disappointed. We learn more about Tony Stark's background, new characters are introduced, and there's plenty of action that keeps it exciting. Robert Downey Jr. gives it 110% of course, and I really enjoyed the relationship between Tony Stark and Don Cheadle's character. I think the choice of Mickey Rourke as the bad guy is perfect. It was fun and enjoyable escapism!
